As things are right now the code wont compile unless you use pthreads or no threading 
at all (See ticket #2422).

So the code either needs to be changed to allocate the mutexes dynamically (Which will
let us use the wrappers), or we make configure abort when trying to build with OpenCL 
support and w32threads or os2threads enabled.

Ideally, the latter if implemented should be a temporary solution until the former is 
implemented instead.
